{snip} - Your list of the biblically-satisfying number of unknowables (or
only theoretically knowables) is interesting. I have some thoughts about
that which I'll save for a later post if sometone else does not express
them first.

> Is it the A-theorists that don't believe the future exists?

A-theorists believe that there is an ontological (not merely epistemic)
asymmetry between past and present, on the one hand, and the future on the
other. The past and the present are real, while the future is not.

Claims of knowledge about future contingent events must, for us
non-omniscient humans, always be hypothetical, unless revealed to us by God.

The fundamental issue here is not what can be known but what exists. There
is always the danger of conflating epistemic with ontological claims.
Knowing how long it will take a steel ball to fall from the top of the
Gamow Tower (in the physics building here at the University of Colorado) to
the sidewalk below is one thing (which still must be qualified by a number
of assumptions); the actual fall of the ball is something else. Even a bit
of knowledge which we hold with very high confidence is quite different
from the actuality or reality of that which we have knowledge about.
